The brand is also committed to getting a worldwide ban on animal testing.

ASOS, one of the biggest online fashion and beauty retailers, has just made a big step in the name of cruelty-free fashion and animal welfare. The online fashion retailer is banning the sale of cashmere, mohair, silk, and feathers across its entire platform.

Vogue UK reports that that decision will impact 850 brands as well as ASOS's own label, and that the policy will go into effect by the end of January 2019.

The announcement comes after the brand banned fur, angora, and rabbit hair from its website, reports the BBC.

ASOS has gone a step further by banning silk, cashmere, and feathers. Harper's Bazaar UK reports animals can be subjected to inhumane treatment to get these fibers. For instance, cashmere goats are clipped in the winter when they need their coats to protect them from the cold. Additionally, 6,600 silkworms are required to make just one kilogram of silk, and they're killed in the process by being gassed or boiled alive.

PETA commended ASOS for the update to its animal welfare policy. "PETA applauds ASOS for leading the charge for compassion in fashion," said PETA Director of Corporate Projects Yvonne Taylor. "In response to PETA's campaigns, consumers are changing the face of the industry by demanding that designers and retailers ditch animal-derived materials in favor of cruelty-free alternatives that look great without causing suffering."

Shoppers are also pleased with ASOS's announcement and are sharing their thoughts on Twitter:
